Thin Lenses
A thin lens allows rays to refract but does not allow properties such as dispersion…
AAMC Outline
Spherical mirrors
A mirror is a reflective surface that light does not pass through, made by a…
Conditions for total internal reflection
Total internal reflection happens when a propagating wave strikes a medium boundary at an angle…
Dispersion, change of index of refraction with wavelength
Dispersion is defined as the spreading of white light into its full spectrum of wavelengths.…
Refraction, refractive index n; Snell’s law: n1 sin θ1 = n2 sin θ2
Refraction: when light ray changes its direction in a new medium depending on the incident…
Reflection from plane surface: angle of incidence equals angle of reflection
The law of reflection states that the angle of reflection equals the angle of incidence.…
Sympathetic and parasympathetic nervous systems: antagonistic control
Autonomic responses are mediated by the sympathetic and the parasympathetic systems, which are antagonistic to one another. The autonomic nervous system (ANS)…
Sensor and effector neurons
Sensor or afferent neurons convey information from tissues and organs to the brain, and efferent…
Major Functions
The nervous system has three overlapping functions; sensory input, integration, and motor output.; it is…
Glial cells, neuroglia
Neuroglia or glial cells maintain homeostasis, form myelin, and provide support and protection for neurons…
